CROSS REFERENCE TO RELATED PATENT APPLICATION

This application is a continuation of U.S. application Ser. No. 14/617,621 filed on Feb. 9, 2015 which claims foreign priority to Chinese Patent Application No. 201410046708.0 filed on Feb. 10, 2014, entitled “Video Communication Method and System in Instant Communication”, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technological field of instant communication, and more particularly to methods and systems of video communication in instant communication.

BACKGROUND

With the development of communication technology, people can communicate with one another anytime and anywhere through mobile terminals. Initially, means of communication conducted via terminal devices mainly include: short messaging, multimedia messaging and telephoning. However, their costs are relatively high to users. Along with the development and advancement of technologies such as 3G (3rd-generation, third generation mobile communication technology), WiFi (wireless fidelity), etc., the reduction of network flow charges and the rapid spread of smart mobile terminals, a number of products are developed in the field of mobile terminal communications, which include mobile terminal communication products (for example, instant communication products or other products such as games having an instant communication function).

Unlike the communication methods of short message and mobile phone, the mobile terminal communication products can organize users into a virtual social network, in which the users can communicate with each other, such as sending text/voice messages, pictures and files, etc., and a message can reach the other party in real time provided that he/she is online. This type of virtual social network makes communication between people more convenient and also reduces the communication cost.

However, problems such as inadequate interaction more or less exist in text and voice communications. Therefore, in order for face-to-face communications between two communicating parties in a better manner, existing technologies offer video communication technology. Through this technology, communicating parties may see a video image of the other party on screens of respective terminal devices, and may further use voice chat to talk to each other during a process of communication. This type of video communication technology is commonly used in a communication process between friends who are well-acquainted with each other. However, if two users have not developed a friendship, the users may not want the other to see how they really look for fear that the other may judge him/her by their appearance, or simply because they have concerns about their own appearance. In other cases, even though two users are friends with each other, one of the users may refuse video communication as he/she may not want to over-expose his/her true image during a video communication process.

Therefore, a technical problem that is urgently needed to be solved is: how to satisfy the need of a user to conduct communication via video communication to improve interactivity while avoiding overly exposing his/her true image in certain specific application scenarios, thereby improving a usage rate of the video communication technology and more fully demonstrating functionalities of the video communication.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present disclosure will be described herein with the accompanying drawings in a clear and comprehensive manner. The described embodiments are only a part but not all of the embodiments of the present disclosure. The other embodiments that are obtained by one of ordinary skill in the art based on the embodiments of the present disclosure fall within the protective scope of the present disclosure.

In the embodiments of the present disclosure, in order to enable users to use video communication without worrying about over-exposure of their true images, video image of the users may undergo a blurring operation when the user conduct video communication there between. As such, an image of the other party seen by a user is blurred, and no excessive information is exposed to that user. Meanwhile, an audio device is usually activated during video communication, the users may chat with each other via an audio means. Therefore, communications can be easily realized. The embodiments of the present disclosure are described in detail hereinafter.

First Embodiment

As shown in FIG. 1, this embodiment of the present disclosure provides a method of video communication in an instant communication process. The method is used for conducting video communication between a first user and a second user. More specifically, the method may include the following:

S101 receives a request for video communication.

S102 determines whether to perform a blurred processing on a video image of the first user.

S103 performs the blurred processing on the video image of the first user if affirmative, such that a blurred video image of the first user is displayed in a video dialog window of the second user.

It should be noted that a part or all of the method blocks in the first embodiment may be performed at a client of the first user or at a client of the second user. Alternatively, they may be performed by an instant communication server that provides a video communication service to the first user and the second user. Descriptions are given as follows in terms of different embodiments.

Second Embodiment

The second embodiment of the present disclosure provides a method of video communication in an instant communication process. The method is used for conducting video communication between a first user and a second user. In this second embodiment, each method block is performed at a client of the first user. More specifically, the method may include the following:

First block receives a request for video communication.

The request for video communication in this block may be initiated by the first user or the second user.

Second block determines whether to perform a blurred operation for a video image of the first user.

After receiving the request for video communication, a client of the first user determines whether to perform a blurred operation for a video image of the first user.

A number of determination methods exist, and determination criteria may be set by the first user or the client software. For example, one or a combination of the following determination criteria may be used for determining whether to perform a blurred operation for a video image of the first user:

A: whether the second user is in a first contact list;

B: whether the first user and the second user conduct video communication with each other for the first time;

C: whether the request for video communication includes an indicator instructing a blurred operation for the video image of the first user.

With respect to the determination criterion A, an examination is made as to whether the second user is included in a contact list of the first user (more specifically, a determination may further be made as to whether the second user is included in a buddy list of the first user). If affirmative, this indicates that two users have already known each other or have contacted each other before. In this case, a normal process of video communication may be used, i.e., activating an image capturing apparatus of a terminal device, sending captured video image information of the first user to the second user, and displaying received video image information that is sent from the second user in a video dialog window. If the second user is found to be not included in the contact list of the first user, this indicates that the users may not know each other. In this case, the first user may set this situation as a criterion for performing the blurred operation so as to avoid an excessive exposure of a true image thereof to a stranger.

With respect to the determination criterion B, a video communication record may be set up for the first user. When a user X conducts video communication with the first user, a video communication indicator is set up for the user X to indicate that the first user has conducted video communication with the user X. Based on the video communication record set up for the first user, a determination is made as to whether the first user and the second user conduct video communication for the first time. If affirmative, decision of performing the blurring operation for the video image of the first user is made.

With respect to the determination criterion C, an operation entry of whether to perform a blurring operation for a video image thereof may be provided to the first user. In a specific implementation, the operation entry may be another operation entry different from common video communication operation entries. For example, two buttons may be set up in a user interface at the client, one of which is used for initiating traditional video communication, and the other being used for initiating blurred video communication. If the first user wants to initiate a request for video communication, which is launched via an operation entry that initiates blurred video communication, this shows that the first user desires a video image thereof to go through a blurring operation.

Alternatively, the request for blurred video communication and a request for traditional video communication may share a same operation entry, only that an option of blurred communication is displayed to the user when the first user launches a request for video communication. If the first user chooses that option, this shows that the first user has launched a request for blurred communication. Otherwise, if the first user doesn't choose that option, then this shows that the first user has launched a request for normal video communication.

Alternatively, in a situation that the first user receives a request for video communication from the second user, an option of blurred video communication may be provided to the user at the client of the first user. Likewise, if the first user chooses that option, this shows that the first user has accepted the request for video communication and desires his video image to undergo a blurring operation. Otherwise, if the first user doesn't choose the option, this shows that no blurring operation is needed for the video image of the first user.

In addition, in a situation that the first user receives a request for video communication from the second user, if information associated with the request for video communication has included an indicator of a need of performing a blurring operation, a decision that the blurring operation is to be performed for the video image of the first user is made based directly on the indicator included in the information.

The aforementioned criteria may be used independently or may be used in combination. In a process where a combination of criteria is used, an order for applying the criteria may further be set up. For instance, the criterion A is first determined, and the criterion B is determined if the criterion A is satisfied. If the criterion B is satisfied, a determination is made that the blurring operation is to be performed for the video image of the first image. Specifically, a determination as to whether the second user exists in a contact list of the first user is first made. If affirmative, a determination is made as to whether the two users conduct video communication with each other for the first time. If affirmative, a determination is made that the blurring operation is to be performed for the video image of the first user. As another example, the criterion C is first determined, and if the criterion C is not satisfied, the criterion A is determined. If the criterion A is not satisfied, the criterion B is finally determined. In other words, a determination is made as to whether a request for video communication includes an indicator that is used for instructing a blurring operation for the video image of the first user. If included, a determination is then made as to whether the second user appears in the contact list of the first user. If affirmative, a determination is made whether the two users conduct video communication with each other for the first time. If affirmative, a decision is made that the blurring operation is to be performed for the video image of the first user.

It should be noted that the present disclosure is not limited to the foregoing criteria. One of ordinary skill in the art can design or perform a selection based on the need of a user or the design of an instant communication system. For instance, different criteria or different combinations of the criteria may be designed based on different perspectives such as user interactivity needs, user experience, etc.

Third block performs the blurring operation for the video image of the first user if affirmative, and sends a blurred video image of the first user to a client of the second user, such that the blurred video image of the first user is displayed in a video dialog window of the second user.

In response to receiving the request of video communication and determining that a blurring operation is needed to be performed for the video image of the first user, the client of the first user may directly perform the blurring operation on the video image of the first user, and then send (relay via a server or send in a point-to-point manner) a blurred video image to the client of the second user. As such, the video dialog window of the second user may directly display that blurred video image of the first user. For instance, in a specific embodiment, the video image of the first user shows a mosaic effect. A number of mosaic patterns may exist, and the present disclosure imposes no limitation thereon. FIG. 2 illustrates a mosaic having a mist pattern 200, i.e., making the video image to appear as if a screen of a terminal device is covered with a layer of mist. Therefore, the second user may vaguely sense the first user, and cannot see him/her clearly, thus preventing from exposing too much personal image information.

In an embodiment, as both parties of the communication need to transmit respective video images to the other party in the process of video communication, the client of the second user may also determine individually whether a blurring operation is needed to be performed for a video image of the second user in the above first situation. If needed, the blurring operation is performed directly for obtained captured video image of the second user, and a blurred video image is sent (relayed via a server or sent in a point-to-point manner) to the client of the first user. As such, the blurred video image of the second user may be displayed in a video dialog window of the first user.

In addition, in the first situation as mentioned above, a number of implementations of the blurring operation exist. For example, in one implementation, some primitive pixels may be extracted from each individual image frame in response to obtaining video image frames, and are deleted. As such, a blurred effect is achieved in a processed image frame due to relatively low in pixels. From the perspective of transmission costs, adopting this method reduces an amount of data that is transmitted. Alternatively, in another implementation, the blurring operation may be performed by applying a filtering function on a primitive video image. After performing the blurring operation for the video images, the parties of the communication may send messages to each other in a textual or audio format.

In order to further promote interactivity during interaction, the client of the first user may further determine a region of operation (for example, label 302 as shown in FIG. 3) corresponding to operation information in response to detecting an operation on the video image of the first user, and perform a blurring operation only on a portion of the video image that is outside the region of operation after obtaining the video image of the first user. In other words, when the user performs an operation (for example, performs a sliding operation on a touch screen of the terminal) on an image which has been blurred, this indicates that the user wants to see a video image of the other party clearly. Therefore, along with the operation of the user, a portion of the video image corresponding to a region of operation (for example, a region corresponding to a sliding operation, or a region corresponding to a block selection or clicking, etc.) is displayed clearly. Combined with the aforementioned “mist mosaic” displaying effect, this process is equivalent to modeling a process of “mist wiping”, in which the entire process is similar to covering a terminal device with a layer of mist, and displaying clearly a region that is wiped as the user is wiping. The user can gradually see the video image of the other party of the communication clearly, and thus the vividness of the process is of operation is enhanced, as shown in FIG. 3.

In a specific implementation, the “wiping” process can be realized in many manners. For example, in the implementation that extracts some primitive pixels to achieve blurring, primitive pixels within an operation region may not be extracted and a high density of primitive pixels of the video image is maintained within the operation region. As such, this is equivalent to performing the blurring operation only on a part of the video image outside the operating region. On the other hand, if the blurring operation is realized by using predefined filtering function(s), input parameter values are no longer coordinates of the entire area where the video image is located, and are inputted to the filter function(s) after removing coordinates corresponding to the operation region. As such, this is equivalent to performing the blurring operation only on coordinates corresponding to the input parameters, and a region that is not processed can be displayed clearly. Additionally or alternatively, other methods of performing a blurring operation may be used in a real application, which are not described one by one herein.

With respect to the process of performing an operation on the video image of the first user, a user who performs the operation may be the first user or the second user.

If the first user needs to show his/her partial or whole video image clearly to the second user, then he/she may perform a related operation in a video image display child window in his/her video dialog window. For example, in an event that the terminal device is equipped with a touch screen, the user may directly perform a sliding operation in his/her video image display child window using a finger or a touch pen, etc. Alternatively, the user may use a mouse to perform a block selection in the video image display child window, etc.

For the client of the first user, this is equivalent to detecting that the first user operates on the video image of the first user. Under such circumstances, this is equivalent to the first user voluntarily showing his partial video image clearly to the second user. Thus, in response to determining the region of operation, the client of the first user directly performs a blurring operation only on a portion of the video image that is outside the region of operation, and then sends a partially blurred video image of the first user to the client of the second user. Accordingly, for the second user, what may be seen in the video dialog window thereof is the video image of the first user, a portion of which may be clear and another portion of which is still blurred.

In the second situation as mentioned above, if the second user wants to see part or all of the video image of the first user, the second user may perform an operation, such as a sliding operation or a block selection operation, etc., on the video image of the first user. In an embodiment, the client of the second user first detects this operation performed by the second user at this time. However, in this situation, the client of the second user may first transmit related information of this operation that is performed by the second user to the first user, and ask the first user whether to allow a display of a video image within an area region operated by the second user to the second user. If the first user gives an approval, the video image of the first user outside the region of operation is displayed to the second user. More specifically, the client of the first user may perform the following operations:

1) Receiving a notification from the client of the second user, the notification being used for indicating a detection of an operation performed by the second user on the video image of the first user and the notification including information associated with a region of operation;

2) Sending a query to the first user to ask the first user whether to allow a display of a video image within the region operated by the second user to the second user;

3) If an acceptance message indicating an approval is received from the first user, performing a blurring operation only on a portion of the video image of the first user that is outside the region of operation after obtaining the video image of the first user, and sending a partially blurred video image of the first user to the client of the second user, such that the client of the second user may display the partially blurred video image to the second user.

It should be noted that, regardless of whether the first user or the second user performs an operation on the video image of the first user, the operation may be conducted in the video dialog window of the client. Under normal circumstances, the video dialog window is divided into a first child window and a second child window. An area of the first child window is usually larger than that of the second child window. Under a default setting, the first child window is used for displaying a video image of the other party, and the second child window is used for displaying a video image of his/her own. However, content displayed in these two windows may be interchanged. For example, after performing a swap based on the default setting, the first child window may display the video image of his/her own, and the second child window may display the video image of the other party. In this embodiment of the present disclosure, for the first user, the first child window displays the video image of the second user, and the second child window displays the video image of the first user under a default setting. However, the area of the second child window is relatively small. Therefore, when the first user needs to perform an operation on the video image of the first user, he/she may first perform a swap operation which causes the video image of the first user to be displayed in the first child window, and then perform a specific operation in the first child window. For the second user, a first child window thereof displays the video image of the first user, and a second child window thereof displays the video image of the second user under a default setting. If the second user needs to perform an operation on the video image of the first user, he/she may directly perform the operation in the first video dialog window. If the second user needs to perform the operation on the video image of his/her own, he/she may also perform a swap operation first, which causes the video image of the second user to be displayed in the first child window, and then perform a specific operation in the first child window.

In addition, in this embodiment of the present disclosure, an operation is performed on the video image of the first user in an instance of video communication, information associated with a region of operation may be stored. In this way, the next time when the first user and the second user conduct video communication with each other in a blurred manner, the client of the first user may first determine whether information associated with a region of operation corresponding to the first user is stored. If affirmative, a blurring operation is directly performed only for an area of a video image that is outside the region of operation. A processed video image of the first user may then be to the client of the second user. In other words, when the two users conduct video communication with each other next time, what effect the second user sees in a video dialog window thereof is a video image of the first user, a portion of which is clear and a portion of which is blurred.

Furthermore, it should be noted that, in the process of blurred video communication, if a user operation on the video image of the first user is detected, a determination may further be made as to whether the second user appears in a contact list of the first user. If not, the second user may be added to the contact list of the first user. In an embodiment, prior to adding, the first user may be asked whether the second user is needed to be added into his/her contact list. Upon receiving an approval from the first user, the operation of adding is then conducted. That is to say, in the process of blurred video communication, if one party needs to add the other party as his/her friend, he/she may directly perform an operation on the video image of the other party. For example, in a situation that the terminal device is equipped with a touch screen, a user may directly perform an operation, such as a sliding operation or a clicking operation, etc., in a display region of the video image of the other party in the touch screen. Correspondingly, a backend database or a server end of a client may store triggering condition(s) for adding the other party as a friend. The triggering condition(s) is/are normally described using operation activity information of a user. For example, the operation activity information may be a simple operation type, such as sliding, clicking, or shaking a terminal device, etc. Alternatively, in order to avoid a false positive, more complicated triggering condition(s), such as a trajectory of sliding exceeding a certain length or a number of clicks to be two, etc., may be designed. In short, in response to detecting an operation of a current user performed on a video image, specific information associated with the operation activity may be first obtained. The specific operation activity information may be detected by devices such as a touch screen or other sensors of a terminal device. The client may read the detected information via a corresponding interface.

After obtaining the operation activity information, a determination may be made as to whether predefined condition(s) is/are satisfied, for example, whether an associated operation is a sliding operation within a video image display region, whether the operation is a clicking operation, etc. If the condition(s) is/are satisfied, a friendship between both communicating parties may be established. Specifically, a user ID of the other communicating party may be added to a buddy list of a present user. In an embodiment, the buddy list may need to be stored in the server. As such, a message may be sent to the server such that the server adds the user ID of the other communicating party to the buddy list of the present user. Furthermore, the friendship between the two users is reciprocal, and the server may add a user ID of the present user to a buddy list of the other communicating party.

Third Embodiment

The third embodiment of the present disclosure provides a method of video communication in an instant communication process. The method is used for conducting video communication between a first user and a second user. Each method block is performed by a client of the second user. Specifically, the method comprises the following:

First block receives a request for video communication.

Similarly, the request for video communication in this block may be initiated by the first user or the second user.

Second block determines whether to perform a blurring operation for a video image of the first user.

After the client of the second user receives the request of video communication, the client of the second user may determine whether a blurring operation is needed to be performed for the video image of the first user. A number of implementations of methods of determination exist, which may be the same as those determination methods described in the second embodiment. Implementations may be made by referencing thereto, and are not described in detail herein.

Third block performs the blurring operation for the video image of the first user if affirmative, and displays a blurred video image of the first user in a video dialog window of the second user.

In this approach, in response to receiving the video image of the first user, a client of the first user may directly send the video image to the client of the second user. Upon determining that a blurring operation is needed to be performed for the video image of the first user, the client of the second user performs the blurring operation on the video image of the first user, and displays a blurred video image of the first user in a video dialog window. In an embodiment, under this type of situation, after receiving his/her own video image, the second user may similarly send his/her own video image to the client of the first user directly. In an event that the client of the first user determines that a blurring operation is needed to be performed for the video image of the second user, the client of the first user may first perform the blurring operation on the video image of the second user, and then display a blurred video image of the second user to the first user in a video dialog window thereof.

In this implementation, various ways of processing when the client of the second user performs the blurring operation for the video image of the first user exist. Examples include the foregoing methods, such as extracting some primitive pixels or using filter function(s).

In addition, the effect of partial blurring may also be implemented if the video image of the first user is operated by a user in the process of blurred video communication. In a specific implementation, if the first user performs an operation on the video image of the first user, a process performed by the client of the second user may include the following:

1) receiving a notification from the client of the first user, where the notification is used for indicating that the first user has performed an operation on the video image of the first user and the notification may include information of an operation region of the first user;

2) when receiving the video image of the first user afterward, performing the blurring operation only on a portion of the video image that is outside the operation region, and displaying a partially blurred video image of the first user in the video dialog window.

If the second user performs an operation on the video image of the first user, the first user may be asked whether to allow a display of his/her video image that is partially clear to the second user first. Therefore, for the client of the second user, the following method blocks may be included:

1) in response to detecting an operation of the second user that is performed on the video image of the first user, determining an operation region, and sending information of the operation region to the client of the first user, such that the client of the first user sends a query to the first user to inquire whether the first user allows a display of a portion of the video image that is within the scope of the operation region performed by the second user to the second user;

2) after receiving a response message from the client of the first user and if information included in the response message indicates an approval, performing a partial blurring operation only on a portion of the video image that is outside the operation region after receiving the video image of the first user, and displaying a partially blurred video image in the video dialog window.

In this third embodiment, the information of the operation region operated by the first user may be stored. In this way, next time when the first user and the second user conduct blurred video communication with each other, the client of the second user may first query information of that operation region, and perform a partial blurring operation only on a portion of the video image of the first user that is outside the operation region, which is then displayed to the second user in the video dialog window.

Fourth Embodiment

The fourth embodiment provides a method of video communication in an instant communication process. The method is used for conducting video communication between a first user and a second user. Each method block is performed by a server. Specifically, the method may include the following:

First block receives a request for video communication.

The request of video communication in this block may be sent from the first user or the second user, and is sent from a client of the first user or a client of the second user to the server.

Second block determines whether to perform a blurring operation for a video image of the first user.

After the server receives the request of video communication, of the server may determine whether a blurring operation is needed to be performed for the video image of the first user. A number of implementations of methods of determination exist, which may be the same as those determination methods described in the second embodiment. For example, a determination may first be made as to whether the second user appears in a contact list of the first user. If not, a determination is made that the blurring operation is to be performed for the video image of the first user. Alternatively, if the two users conduct video communication with each other for the first time, a determination is made that the blurring operation is to be performed for the video image of the first user. In another alternative, if the request for video communication includes an indicator for blurred video communication, a determination is made that the blurring operation is to be performed for the video image of the first user. Alternatively, if a request for blurred video communication is received from the client of the first user after receiving the request for video communication, a determination is made that the blurring operation is to be performed for the video image of the first user.

If affirmative, third block performs the blurring operation for the video image of the first user after receiving the video image of the first user, and sends a blurred video image of the first user to the client of the second user, so that the blurred video image of the first user is displayed in a video dialog window of the second user.

That is to say, under this approach, after obtaining the video image of the first user, the client of the first user may directly send the video image to the server. Upon determining that a blurring operation is needed to be performed for the video image of the first user, the server performs the blurring operation on the video image of the first user, and forwards a processed video image to the client of the second user, such that the client of the second user may display on the blurred video image of the first user in the video dialog window.

In an embodiment, in this situation, a process performed by the server for the second user is the same as that performed by the server with respect to the first user, and is not repeatedly described in detail herein.

In this implementation, a number of processing methods exist for the blurring operation of the video image of the first user performed by the server. Examples include the foregoing implementations such as extracting some primitive pixels or using filter function(s).

In addition, the effect of partial blurring may also be implemented if the video image of the first user is operated by a user in the process of blurred video communication. In a specific implementation, if the first user performs an operation on the video image of the first user, a process performed by the server may include the following:

1) receiving a notification from the client of the first user, where the notification is used for indicating that the first user has performed an operation on the video image of the first user and the notification may include information of an operation region of the first user;

2) when receiving the video image of the first user afterward, performing the blurring operation only on a portion of the video image that is outside the operation region, sending a processed video image of the first user to the client of the second user to facilitate the client of the second user to display a partially blurred video image of the first user in the video dialog window.

If the second user performs an operation on the video image of the first user, the first user may be asked whether to allow a display of his/her video image that is partially clear to the second user first. Therefore, for the server, the following method blocks may be included:

1) receiving a notification from the client of the second user, where the notification is used for indicating that the second user has performed an operation on the video image of the first user and the notification may further include information of an operation region of the second user;

2) sending the information of the operation region to the client of the first user, such that the client of the first user sends a query to the first user to inquire whether the first user allows a display of a portion of the video image that is within the scope of the operation region performed by the second user to the second user;

2) after receiving a response message from the client of the first user and if information included in the response message indicates an approval, performing a partial blurring operation only on a portion of the video image that is outside the operation region after receiving the video image of the first user, and sending a processed video image of the first user to the client of the second user to facilitate the client of the second user to display a partially blurred video image of the first user in the video dialog window.

In the fourth embodiment, the server may store the information of the operation region performed by the first user. In this way, next time when the first user and the second user conduct blurred video communication with each other, the server may first query information of that operation region, perform a partial blurring operation only on a portion of the video image of the first user that is outside the operation region, which is then sent to the client of the second user and is displayed by the client of the second user in the video dialog window.

Fifth Embodiment

The fifth embodiment of the present disclosure provides a method of video communication in an instant communication process. The method is used for performing video communication between a first user and a second user. Referring to FIG. 4, the method may include the following method blocks:

S401: A client of the second user sends a request of video communication to a client of the first user.

In this block, the second user actively sends a request of video communication to the first user. Specifically, the second user may send the request of video communication via a client of the second user to a client of the first user.

S402: The client of the second user receives a video image of the first user, the video image of the first user having undergone a blurring operation performed by the client of the first user.

in this block, the client of the second user receives the video image of the first user. After receiving the request of video communication, the client of the first user may follow the procedure of determination in the second embodiment (specific condition(s) of determination may be designed or chosen in accordance with the user′ need and the design of the instant communication system). When the condition(s) of determination is/are satisfied, the client of the first user performs a blurring operation on the video image of the first user, and then sends the blurred video image to the client of the second user. As such, the client of the second user receives the video image of the first user which has been undergone the blurring operation.

S403: The blurred video image of the first user is displayed in a video dialog window of the second user.

Furthermore, when the first user and the second user conduct video communication with each other, the process may further include:

Block A1 determines a region of operation corresponding to operation information in response to detecting that an operation is performed on the video image of the first user.

If the second user desires to see a larger portion of the video image of the first user, the second user may perform an operation on the video image of the first user that is displayed in the video dialog window of the second user so as to determine corresponding information associated with the region of operation. The method of determining the region of operation may employ the method of determination as described in the first to fourth, and is not redundantly repeated herein.

Block A2 sends a query message including the information associated with the region of operation to the first user. The query message is used for inquiring the first user whether to allow performing a blurring operation only on a portion of the video image that is outside the region of operation.

Upon determining the region of operation, the client of the second user may send a query message including the information associated with the region of operation to the client of first user to inquire the first user whether to allow performing the blurring operation only on a portion of the video image that is outside the region of operation. The first user may choose to agree or disagree according to a chatting status after receiving the query message.

Moreover, when the first user allows performing the blurring operation only on the portion of the video image that is outside the region of operation, the video image of the first user received by the second user is a video image having the blurring operation performed only in a video image area that is outside the region of operation.

Specifically, in response to receiving a response that allows the blurring operation to be performed only in for a portion of the video image that is outside the region of operation from the first user, the client of the first user performs the blurring operation on the portion of the video image of the first user that is outside the region of operation, and sends a processed video image to the client of the second user. The video image of the first user that is received by the client of the second user is a video image which has been blurred in a video image area that is outside the region of operation. The video dialog window of the second user displays the video image of the first user which has been blurred in the video image area that is outside the region of operation.

In short, using the embodiments of the present disclosure, a blurring operation may be performed for video images of both communicating parties in a process of video communication between two users. In this way, convenient online communication may be achieved via video communication while ensuring that respective privacies of the users are not overly exposed.

In addition, when a user intends to add the other party as a buddy, he/she may perform an operation on a blurred video image. Correspondingly, if the operation satisfies predefined criteria, a friend relationship between the two parties may be set up, thus reducing an operation path of the user to add the other party as a buddy and enhancing the efficiency thereof.

Corresponding to the methods of video communication in the instant communication process provided in the embodiments of the present disclosure, the embodiments of the present disclosure further provides a system of video communication in an instant communication process, which is used for performing video communication between a first user and a second user. Referring to FIG. 5, the system may include:

a request receiving unit 501 used for receiving a request for video communication;

a determination unit 502 used for determining whether to perform a blurred processing on a video image of the first user; and

a blurred processing unit 503 used for performing the blurred processing on the video image of the first user when a determination result of the determination unit 502 is affirmative, such that a blurred video image of the first user is displayed on a video dialog window of the second user.

In a specific implementation, the system may further include:

a detection unit, used for determining a region of operation corresponding to operation information in response to detecting an operation on the video image of the first user; and

a partial blurring unit, used for performing the blurring operation only in a video image area outside the region operation for an obtained video image of the first user.

If an operation performed by the first user on the video image of the first user is detected, the partial blurring unit directly performs the blurring portion on the video image area of the first user that is outside the region of operation.

If an operation performed by the first user on the video image of the first user is detected, the partial blurring unit may include:

a query subunit, used for sending a query message to the first user, the query message being used for inquiring the first user whether to allow the blurring operation to be performed only on the video image area that is outside the region of operation; and

a processing subunit, used for perform the blurring operation only on the video image area that is outside the region of operation in response to receiving a responses indicating an approval.

In addition, the system may further include:

an information storage unit, used for storing information associated with the region of operation;

a query unit, used for querying whether the information associated with the region of operation for the first user is stored if the blurring operation is to be performed for the video image of the first user when a new request for video communication is received; and

a processing unit, used for performing the blurring operation only on the video image area that is outside the region of operation if the information associated with the region of operation for the first user is stored.

In a specific implementation, after performing the blurring operation on the video image of the first user, the client of the first user sends the processed video image to the client the second user, such that the video dialog window of the second user displays the blurred video image of the first user.

Alternatively, in another specific implementation, the client of the first user sends the obtained video image of the first user to the client of the second user, such that the video dialog window displays the blurred video image of the first user after the client of the second user performs the blurring operation on the video image of the first user.

In a specific implementation, the determination unit 502 may be used for:

determining whether the blurring operation is needed to be performed for the video image of the first user based on one or more of the following criteria:

whether the second user is included in a first contact list;

whether the first user and the second user conduct the video communication with each other for a first time; and

whether the request for video communication includes an indicator that instructs the blurring operation to be performed for the video image of the first user.

In correspondence with the fifth embodiment, the embodiments of the present disclosure further provide a system of video communication in an instant communication process, which is used for performing video communication between a first user and a second user. Referring to FIG. 6, the system may include:

a request sending unit 601 used for sending a request for video communication to a client of the first user from a client of the second user;

a video image receiving unit 602 used for receiving a video image of the first user by the client of the second user, the video image of the first user having been undergoing a blurred processing by the client of the first user; and

a display unit 603 used for displaying a blurred video image of the first user in a video dialog window of the second user.

Moreover, the system may further include:

a detection unit, used for determining a region of operation corresponding to operation information in response to detecting an operation on the video image of the first user; and

a query unit, used for sending a query message including information of the region of operation to the first user, the query message being used for inquiring the first user whether to allow the blurring operation to be performed only on an video image area that is outside the region of operation.

When the first user allows the blurring operation to be performed only on the video image area that is outside the region of operation, the video image of the first user received by the video image receiving unit is a video image having the blurring operation performed only on the video image area that is outside the region of operation.

In short, using the embodiments of the present disclosure, a blurring operation may be performed for video images of both communicating parties in a process of video communication between two users. In this way, convenient online communication may be achieved via video communication while ensuring that respective privacies of the users are not overly exposed.

In addition, when a user intend to add the other party as a buddy, he/she may perform an operation on a blurred video image. Correspondingly, if the operation satisfies predefined criteria, a friend relationship between the two parties may be set up, thus reducing an operation path of the user to add the other party as a buddy and enhancing the efficiency thereof.
